## Overview

BlueDevil Rear Main Sealer is an 8-ounce liquid additive designed to permanently repair rear main seal leaks by flowing into damaged areas and restoring rubber seals while driving. Compatible with all engine types and oils, it offers a safe, easy-to-use solution that prevents costly repairs and keeps your engine oil where it belongs.

## Description

BlueDevil Rear Main Sealer is a product designed to fix leaks in the rear main seal of an engine. The rear main seal is a critical component of an engine, as it helps to keep the oil inside the engine and prevent it from leaking out. Over time, the seal can become worn or damaged, leading to leaks. Bluedevil Rear Main Sealer is formulated to be a non-particulate sealant that can mix with the engine oil and flow into the damaged areas of the rear main seal, creating a permanent seal. It is designed to work with all types of engine oil and can be used in both gasoline and diesel engines.

Review: THIS STUFF WORKS!! - I have a 2009 F150 with over 337,500 miles on the original engine. It developed a persistent rear main seal leak about a year ago. Having called the local dealer, I was quoted labor only of $1,900 to repair this leak. I went on desertcart to see if there might be anything out there that would help. I purchased this Blue Devil pour and go rear main sealer and had it delivered next day, put it in the crankcase as instructed and drove to Ft. Lauderdale (200+ miles roundtrip) So far, after about 400 miles, it looks to me that the leak has stopped. I'm hopeful that it stays stopped and will no longer be a mess on my paver driveway!! I recommend this product based on this outcome.
Review: Good buy! - Blue Devil has always been a great product!!

### ⭐⭐⭐⭐ Slowed down the leak but.....still leaks
*by B***N on December 26, 2023*

Ok so I have a 2008 Cadillac Escalade EXT. 6.2 and all wheel drive. About 100K miles and it has had a minor oil leak for about a year or two. Talking a couple drops on the driveway overnight. Then after a road trip towing my camper around 200 miles total I did an oil change and the next day the oil leak was massive. The day after changing the oil I got the "low oil pressure, shut off engine!" alarm. It was at that point I cold see oil dumping out while idling. It was a consistent drip to the tune of 2 quarts a day on my daily commute which is only 30 miles total. Upon searching for the source I was able to see it was the rear main seal. I tried the Blue Devil RMS product. It did slow the leak but I was still losing at least a quart of oil every 30 miles or so. Now my truck is in the shop getting the rear main seal replaced. This job calls for the transmission, transfer case, cross members, drive shafts and exhaust system to be removed to replace this $30 seal. While the truck was at the shop and the trans removed I asked the shop to change the oil pan gasket as well because with my luck the oil pan gasket would start leaking a month later. Total cost is $2,000 for the rear main seal and oil pan gasket. I wish the sealer would have worked, but I guess my leak was way too much for it.
